Suspicious of Croats on both political and religious grounds, his ideal was a “Greater Serbia”, including much of Croatia and Dalmatia, with Serbs the master race. However, he signed the Corfu Pact (1917) which resulted in a union of Serbs, Croats, and Slovenes into a new kingdom which he represented at the Versailles Peace Settlement (1919). He was twice Premier of the new kingdom (1921–24; 1924–26), which adopted the name Yugoslavia in 1929.
